Another object of the in' ention is the provision of novelgauging means ier separating vials of several lengths.

Other objects will be apparent from the following description of the apparatus taken in connection with the accompanying drawings, in

In the drawings, the frame of the machine is shown at l0 and comprises side members H and legs l2. Bracket plates 13 are .bolted on legs I2 and form journals for shafts l4, M, on which are keyed pulleys l5, I5. Shaft M is driven through belt l6, chain It, reductor H, and motor l8, cone pulleys l9 providing for a variety of belt speeds. Belt tightener or idler adjustably fixed on rod 2| insures engagement of the conveyor belt 22 with the pulleys.

At the forward end of the frame there is secured thereto an inclinedho per 23 adapted to over the pulleys and idler is horizontal.

It will be seen from the drawings that the faceof that portion of the'conveyor belt passing During the gauging stage, however, the belt 22 is so twistthe ed that the face of the belt is substantially .ver-

Guide bar 42 is weldedto a pair of straps 43, 43., bolted to a block 44, the latter forming a rest for the rear face of the conveyor belt and being secured to the frame by bolts 45.

It should be noted that bar 42'is so spaced from block that the conveyor belt is held against the block for sliding engagement thereover. Further to guide the belt are a pair of rollers 45 so separating chutes 43 underlying the gauging blades 35.

The operation of the machine isas follows:

Eachblade removes vials depending on their lengths so that the vialsare sorted into batchesjthose in each batch being approximately the ,samelength'. It is thus possible toseparate vials which fall within prescribed limitsfrom those'the length of which is greater or. less-than the dimensions required by the trade.

The machine has been described in some detail, but it is to be understood that changes therein may be made without departing from the principles of the invention. i i

Having described my invention, what I claim as new'an d desire to secure by Letters Patent is: -1. Apparatus for separating glass vials of varying lengths comprising a belt conveyor, means projecting from said belt for. spacing and main taining the vials in parallel relation thereon, a pair of spaced horizontallydisposed pulleys supporting said belt in a portion of its course, a guide member supporting the face of said belt in a.substantially vertical position in another portion of its course,,means for guiding said belt toturn the face thereof fromits horizontal position to'its vertical position and for holding said belt against said guide member, means for depositing the vials on a horizontal portion of said belt, and meanspositioned above the vertical portion of the belt and engageable with vials of a predetermined length to remove vials so engaged from the belt.

2. Apparatus for separating glass vials of varying lengths comprising a belt conveyor, means projecting from said belt for spacing and maintaining the vials in parallel relation thereon, a pair of spaced horizontally disposed pulleys supporting said belt in a portion of its course, a guide member supporting the face of said belt in a substantially vertical position in another pbrtion of its course, a plurality of twisted bars for guiding said belt to turn the face thereof from its horizontal position to its vertical position and for holding said belt against said guide member, meansfor depositing a single vial on the horizontal portion of said belt between each of the'belt and engageable with progressively I :shorter vialsto remove vials so engaged from the belt.

3. Apparatus for separating glass vials of varying lengths comprising a belt conveyor, means projecting from said belt for spacing and maintaining the vials in parallel relation thereon, means for guiding said belt with its face in a substantially horizontal position in a portion of its course and in a substantially vertical position in another portion of said course, certain of said guidingmeans, acting as a support for the vials, means for depositing vials on said belt,. and a pluralityof means positioned above the vertical portion of said belt at predetermineddistances above said support and engageablewithprogres sively shorter vials successively to remove vials so engaged from the belt. l

4. Apparatus for separating glass vials of varying lengths comprising a belt conveyor, means rojecting from said belt for-spacingand maintaining the .vialsin parallel relation thereon, means for guiding said belt with its face in a substantially horizontal position in a portion of its course and in a substantially vertical position in another portion of itscourse, said guiding means including a pair of spaced twisted bars, means for depositing the vials on a horizontal portion of said belt, one of said bars serving as a support for the vials when the face of the belt is in its vertical position, and-means positioned above the vertical portion of the belt and engageable with vials of a predetermined length to remove vials so engaged from the belt. 1 i
